　　 One day, I was reading a book and eating an apple. I had read this book twice before.
　　 一天，我正边吃苹果边看书。这本书我已经读过两遍了。
　　 Suddenly, a book fell off bookshelf and hit me on the head. I saw a little rat on the top of the shelf. But,it ran away immediately. I got angry with this rat. I took a bottle of liquid medicine to kill the rat. I put the liquid medicine on the apple and put the apple in the corner. I sat quietly staring at the apple. Then the rat found this apple. The rat died before it ate up the apple. I felt very proud.
　　 突然，一本书从书架上掉了下来，砸中了我的头。我看见书架顶上有一只小老鼠，但是它很快就逃走了。我很生气，便拿来一瓶灭鼠药想要毒死它。我把洒了药水的苹果放在墙角，静静地盯着苹果。之后，老鼠发现了苹果。老鼠还没吃完苹果，就死了。我感到非常自豪。
